All your line data should be in the same IAxisChartDataSet; it takes a double[][] for the data
values.

Each IAxisPlotDataSet in the DataSeries Object represents a specific kind of chart.

[jCharts-users] LineCharts Question multiple data series...

[Daniel H. <Dan...@di...>]

Being a newbie to the JCharts, I am having difficulty getting a graph to =
correctly display multiple lines of data, and have not been able to find =
an example that does this.

I see http://jcharts.sourceforge.net/samples/line.html shows a sample, =
but no code is provided.

I have played/modifed the code from ComboChartServlet example, where I =
simplied added another data series, but this too fail, unless the second =
data series is configured to render using ChartType.BAR

The modified service method is shown below...

If I modify the one of the lines:

dataSeries.addIAxisPlotDataSet( new AxisChartDataSet( data, =
legendLabels, paints, ChartType.LINE, this.lineChartProperties ) );

to

dataSeries.addIAxisPlotDataSet( new AxisChartDataSet( data, =
legendLabels, paints, ChartType.BAR, this.barChartProperties ) );

it will render this series correctly as a bar chart, and the other as a =
line chart.  But I cannot get them both to render as lines..what gives?

I must be missing something....any suggestions would be greatly =
appreciated

>  1. Email Notification and Reports via email.
This is not built into jCharts as jCharts is not a reporting or notification system. You could use
jCharts in a report and send email via the JavaMail API.


>   2. Preview Report support
Again, jCharts is not a reporting package.  Take a look at JasperReports for a robust reporting
java based reporting package.  We have a download on our site which shows how to integrate the
two.

This is not available right now, although I have started work on this a while back.

We do not load properties via files, although you could do this. Then create a static instance of
the Properties Object and use the same instance in all of your charts.

anywhere Java runs

RE: [jCharts-users] Jchart Features

[Vikram R. <Vi...@PL...>]

hi Raketla,

jCharts requires atleast JDK 1.3.1 and JDK 1.4.
Hence jCharts can be used on all platforms that have these JDKs' support. It
runs well on all the platforms you have mentioned.
jCharts can be made to run on pretty much most application servers. 

jCharts does not have the first 4 features that you have mentioned.

There is the ability to do client side image maps from jcharts. What you choose to do with the
image maps is up to you.  Fly throughs of the data is not supported.


> 3. BLOB Bitmap support.

jCharts is database independent; we simply utilize the Paint interface. Take a look at thffe
java.awt.TexturePaint implementation.

Can you see any of the jCharts Classes?  If you comment out the ChartFont call do you get a

How did you verify your classpath on the server?  Are you sure you have the right version of
jCharts on the ClassPath?  This looks like a classpath issue.

This is the section from the user guide:

User Defined Scale
By default, the value Axis will compute a scale range that includes all points in the data set and
is rounded to the power of ten specified.

Make note of that last statment. If you enter a scale increment of 35 and use a rounding value of
100, your increment will become 100.

The following example sets the axis to start at -2000 and go up in increments of 850. It also sets
the rounding factor to the nearst 0/100 or 10 to the 0'th power, so we will see increments of 850.
Had this been left at the default value, the increment would have been 900.

code:
AxisProperties axisProperties= new AxisProperties();
DataAxisProperties dataAxisProperties= (DataAxisProperties) axisProperties.getYAxisProperties();
dataAxisProperties.setUserDefinedScale( -2000, 850 );
dataAxisProperties.setRoundToNearest( 0 );

Take a look at the User Guide for a Combo Chart for Lines over Bars.

You could use the date set interfaces to create your own implementation, or you could simply have
your own List and convert that to an array of double[][]

[jCharts-users] running out of time

[Mike E. <mi...@mi...>]

Hi,

I'm sorry to ask this, but I need some help.
At the bottom of this message is what I have so far.
The code does plot, but the scaling is not limited to
only the numbers around the input data. The scaling
starts from zero and goes up from there. I only want
the area around the input data.

Once that gets fixed I next need to overlay lines
on top of the stock bars, then I need to limit the
chart to plotting only data in a specific range at
the end of the dataset (only the most recent data),
or to through code remove the oldest datum in the
dataset as the newest datum is pushed on.

Can anyone help me or point me where I need to travel
to accomplish this task?

Mike

Yes, just pass NULL as the LegendProperties.

take a look at: http://jcharts.krysalis.org/userGuide/legendVisibility.html

This feature is the same across all chart types.

Post your sample to this list and we will have a look at it.  Perhaps this would be a good example
for the User Guide?

Even if it does not get included, posting it here could help other people out too.

[jCharts-users] Pie Chart with Legend Labeld in Chart but no legend

[<pas...@ne...>]

Hi,

First let me say thanks a million to those who wrote JCharts.
I am looking forward to contribute to the project in the very
near future.

I have a pie chart, and I display the legend values to
display nice labels around the slices.  But I would like
not to display the legend.

Is that possible?

Thanks,

Pascal Forget


P.S. I wrote a Java servlet which generates a pie chart
on the fly based on the http request received.  Everything
in the chart including the values, legend, slice colors,
fonts and title are provided URL-encoded as part of the
request.  If you guys ever need to add this to the sample
code that's bundled with JCharts, let me know.

[Rainer R. <rai...@at...>]

It took a little longer than anticipated but I finally got around to 
checking this out on a different platform. The news is that this 
problem is indeed specific to Apple's implementation of JDK 1.4.1. When 
I ran my app on Windows XP with Sun's JDK (also 1.4.1) the chart looks 
perfectly fine.

Nathaniel: Are you interested to bring this problem to Apple's 
attention or do you not care about that platform. If you're interested 
we could work on isolating the problem in more detail and submit a bug 
to Apple.

Cheers,

Rainer

Not yet.  I just brought back the 3d pie from jcharts 0.2 (still have a little work to do).  A 3d 
looking bar would not be too difficult to implement.  A cheap way to do it would be to simply draw
a bar several times(depth), off setting one by a pixel down and to the side.  Sort of sliding the
bar without clearing the image.  Simply trap the first and last to draw a border, then draw the
other edges. (see attached 3d pie chart)

Same approach, but subdivide the depth by the number of bars in each cluster for a clustered 3d
look.

[jCharts-users] 3D charts in their infinite variety

[Chris M. <ch...@de...>]

Hi,

A couple of questions for users of Jcharts, looks pretty slick BTW.

Has anyone done any work on rendering the bar charts in a 3D look? I'm
guessing this could be implemented using a custom renderer? Am I on the
right track?

Now for something tricker: What about 3-d, for example y-axis plots a
value, x-axis plots the days, and z-axis plots the hours within the day
?

Any info would be greatly apprciated,

Regards, Chris

[jCharts-users] jCharts 0.7.4 has been released!

[Nathaniel G. A. <nat...@ya...>]

In porting the User Guide over to using Forrest, I have found a couple minor bugs which are
significant enough in my opinion to warrant another patch release to the 0.7.0 tree.


# Fixed Bug: The Y-Axis Title was not centering itself vertically on the y-axis.
# Fixed Bug: multi-line chart title not computing its height correctly.

hey Rainer,

Give the new JDK 1.4.2 a try to see if this resolves your problem.
